ADDING AND LISTING MACHINE. ,r

Application led 4August 15, 1921.V Serial-No. 492,242.

Machines embodying the present invention are especially useful in' retail stores where it is desirable to give each customer a slip showing the various items of his purchase, toget er with the total of theitems,

and to preserve a record ofthe items of all sales.

Certain machines now on the market arov adapted to record items and totals' upon two tapes wound face to face, the rear face of the vtop tape being carbonized. Portions of the upper tape are torn oli and handed to the customers, the other tape bein rewound inpable of producin customers slips showingtheI items and tota of a purchase, anda record for the proprietors use of the items of all sales made durin the day, without the necessity of using car onized paper; to pro# vide means whereby the total sales may be ascertained at the end of the day or at any other desired time by a simple operation of the machine; and to provide means to prevent any unauthorized person from operating the machine to ascertain the total sales.

` In the accompanyin drawings Figure 1 is a fragmental longitu mal vertical sectional view of -a machine embodying the features of my invention. Fig. 2 is a fragmentalhorizontal sectional view of the machine. Fig. 3 is a horizontal sectional view of a portion of the setting-up mechanism. Fig. 4 is a rear elevation, that is to say, a view taken in the plane of line 4-4 of Fig. 3. Fig. 5 isa vertical sectional view taken approximately in the plane of line 5-5 of Fig. 1 and line 5 of Fi 2. Figs. 6 and 7 .are detail views of a loc.

' comprised in the machine. Fig. 8 is a facsimile of some printing done upon the machine. Fig. 9 is a.v fragmental front elevation of the hammer mechanism. Fig. l10 is a front elevation of the totaliz'ers.

For convenience in imparting an understanding of the invention, the same will be herein described as embodied in a ten-key adding and listing machine substantially similar to the one shown in Patent No. 1,198,487

issued September 19, 1916, to Rockford Mill- Ing Machine Compan upon an application tiled' by Gustat Davi Sundstrand, but it should be clearly understood that the present Invention is not limited to machines of the general character disclosed in .said patent. In a machine embodying this invention, the sheet or tape or tapes on which the items -and totals are' to be printed may be^su ported by any ordinary 'or suitable means, t e only portion ofI such sup orting means herein shown being a cylindrical laten 2.,

The machine shown in t e drawings comprises two sets of vertically reciprocable type bars, the left-hand set being-ada ted to prmt the items and the total of each sa e, and the right-hand set beino' adapted to print the items of each sale and the total amount of all sales. In the present instance, there are four type bars in t e left-'hand set and s ix in the right-hand set, the machine therefore being capable of recording individual sales not exceedin $99.99 and of recording total sales not exceeding $9,999.99. `It will be evident, however, that the invention may be embodied in a machine having a greater orfsmaller number of type bars.

type bars for adding all items introduced 4 into the machine. Means is provided in conj unctionwith the left-hand totalizer for automatically obtaining totals, which means may be of any suitable character, as, for example,

that disclosed in said Sandstrand atent. In connectionv with the ri ht-han totalizer there is' a special key for o taining totals. A clearing key is provided for clearing either or both totalizers.

The type bars of the left-hand group are designated 3L inthe drawings, while those of the right-hand group are marked 3R. One bar is provided for each numerical order. Each type bar supports at its upper end ten type-carrying plungers 9 adapted to print from 0 to 9, respectivel The top plunger. isadapted to print 0 the next to the top l, and so on.

The means for vertically moving each type bar into and out of printing position may be of any suitable construction, as, for example,

versely of tlle maelline.

In t e movement of the slide 47 to the initial position, the stops 42 that had been set are ushed forward to the initial position by two ars 81- fixed to the slide 47 said bars having inclined faces which engage the stops. i

The repeat ke mechanism employed in the ing machine, may be provided, if desired. v

The means for driving the type-carrying plun ers 9 into contact wlth the inking ribbon mayie similar to that embodied in the wellknown Sundstrand adding machine or-of any other suitable construction, and hence its construction and arrangement needl not be disclosed herein in detail. The general construction of the hammer mechanism of the Sundstrand adding machine is explained inmy Patent No. 1,626,889, dated May v3, 1927, to which reference may bemade for a full understanding of its construction and operation. In the present drawin 386 are. the hammers and 400 the controlling levers. The means for etfecting the release'of the hammers that are to print ciphers comprises the usual lugs 408. It ywill be understood that the hammers for the left-hand group of type barsoperate independently of the hammers for the right-hand set of type bars, and vice versa, there being no lug 408 on the controlling lever for the hammer which corresponds tothe type bar 3R that is nearest to t e ,type bars 3.l (See Fig. 9).

` As heretofore stated, lthe adding mechanism v and said frame is swung rearwardly just be` fore the type bars are moved downwardly.- AAddition therefore occurs in the .down-stroke of the type bars, the extent of rotation of the pinions depen'dingrof course, upon the extent of movement of said bars.

It sometimes is desirable to print an item without adding it to the amount already accumulated. This may be accomplished by means such as that disclosed in said Sundstrand Patent No. 1,198,487, said means in-` cluding a non-add key 152 and connections whereb the pinions stay out of mesh with the racks uring the downward stroke of -the type bars.

he carrying lmechanism maybe similarto that disclosedin said Sandstrand Patent No. 1,198,487 or of any other desired construction, and therefore its construction and operation will not be vdisclosed herein inl detail.

When atotal is to be printed, the pinions I are retained in mesh with the racks durin the upward movement of the type bars, as ully explained in said Sundstrand patent.

The means present in the well-known Sundstrand adding machine isv employed to print.

When Said rod is slid rearwardly through depression of the total key 460, the rear end of the rod engages pulled, saidtype bars rising to the extent per' mit-ted .by the pinions .of the right-hand totalizer, whereby the total accumulated in said totalizer is printed.

When it is not desired to clear the righthand totalizer after printing a total, the pin- 'ions are allowed to remain in mesh with the racks during4 the downward or return movement of the latter-L v Whena grand totalis to be taken from either totalizer, itis necessary to operate al clear key 466, this key andits connections to the swinging frame 127 being identical with the total key and connections employed in the wellknown Sandstrand adding machine; or it may be of any other desired nature.

When a grand total is to be taken from the left-hand totalizer only, the clear key 466 is depressed, but the total key 460 'is not operated, conse uently the right-hand set of type barsis hel stationary by the detent plate 450. By reason of the depression of the clear key 466, the ttalizers are moved out of engagement with the racks after the completion of the u stroke of the racks 3L and before said rac s descend, thus leaving all of the pinions of the left-hand totalizer standing at zero.

As will be understood, when a subtotal is to be taken from the right-hand totalizer, the total key 460 is depressed, but the clear key 466 is not operated.
